WEATHER-STRIP.

Specification of Letters Patent.

Patented July 6, 1920","`

Application filed March 12, 1918. Serial No. 221,976.`

To all 'whom t may concern Beit known that I, CHARLES D. SHAFER,

a citizen of the United States, residing at Escatawpa, in the county of Jackson and State' of Mississippi, have invented certain new and useful Improvements in Teather-Strips, of which the following is a speciication.

This invention relates to weather strips and has for its primary object to provide a weather strip for use primarily on the under side of swinging doors and windows and when such door or window is'closed to contact with the sill thereof and form" a closed joint therewith to prevent the en? trance of rain or wind. i

A further object of the invention is to provide a weather strip of metal designed to be partly seated within a groove in the underside of a swinging door or window and supported in such position to swing to and from the bottom of the door and maintained when out of use against the bottom of the door by suitable resilient means and adapted to coperate yat its end or ends with a lug or lugs on the frame when the door or window is closed for the purpose of depressing or rocking the weather strip into contact with the sill and so form a tight joint.

With the above objects in view, the invention consists in the novel construction, conibination and arrangement of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, in which z- Figure 1 is a vertical sectional view through the lower portion of a door and the door-.sill with the improved weather strip in position and shown in contact with the door sill to prevent the entrance of air or water into the room.

Fig. 2 is an elevation partly in section on the line 2-2 of F ig. 1.

Fig. 3 is a sectional view through the lower portion of the door with the weather strip in elevated position and out of use.

Fig. 4 is an exterior view of one corner of a door and door frame with the weather strip applied and in use, and,

Fig. 5 is a detailed perspective view of one end of the weather strip showing the means for depressing or rocking the strip into its operative position.

In the drawings, 10 indicates a swinging door and 11 the sill therefor, the door, being mounted on hinges to swing in a frame 12, has formed in its Abottom edge a groove 13 extending the full'width of thefdoor. lVith- .in the groove 13 is seated a weather strip 14 formed of astrip of sheet metal as long as the door is wide and'A bent into U-shape 1n cross section as shown in the drawings, one side 15 being wider or projecting `a greaterdistance beyond the bend 16 than the other side 17. Through the side ofthe strip 17 nearthe bend 16 are a series of per- '.forations 18 spaced apart to receive lfasteningscrews 19 that hold the strip in position on the bottom of the door. For convenience of inserting thescrews perforations 20 are formed vinthe side vofthe strip 15 inline with theperforations 18 to permit insertion of a screw driver for forcing the screwsy into=Y the door. The screws 19 do not securev4 the strip rigidly in place, but project a short distance into the slot 13 so that vthe strip will rest upon the heads of the screws and be supported thereby, a short space being left between the strip and the bottom of the groove to permit the strip to rock freely on the screw heads, said strip being held in a substantially horizontal position as in Fig. 3 with the part 15 in contact with the underside of the door by two or more flat other Vshaped springs 21, each secured at one end to the bottom of the groove 13 and bearing at its` other end on the curved portion 16 of the strip serving thereby to depress said portion and raise the outer free edge of the part 15 that when in use contacts with the sill 11. When the door is swung away from the sill 11, the springs 21 hold the part 15 in contact with the bottom of the door and so permit the door to swing freely, but when nearly closed, fingers 22 on one'or both endsof the part 15 of the weather strip engage under a lug or lugs 23 secured to the door frame and cause said weather strip to swing `downwardly until the outer edge of the part 15 bears upon the sill 11, thus forming a perfect flashing for the bottom of the door and keeps wind v and water from blowing under the door into the building.

In applying the strip to a door having a groove 13 in the bottom, the narrower part 17 of the weather strip is seated in the 'groovel 13 after the springs 21 have been placed in position, and the screws 19l driven in suiiiciently far to hold the strip in place and the springs under tension, which as previously stated, bear upon the curved portion 16 of the weather strip and so raise the outer free end of the part againstthe underside of the door. rllhe lug or lugs 23 are now fastened to the door frame just above the door sili and in such position that the forward beveled end thereof will be in position to enga-ge the finger or fingers 22 on the weather strip and depress the latter against the sill ll when the dooris fully closed. l/Vhen the door is opened, these .fingers swing away from thelugs and permit thesprings 2l to again return the weather strip to its inoperative position.

What claim is: I In Combination with a Closure having a groove in an edge thereof, a weather strip oomprisi ng narrow and wide elements spaced apart and Connected at corresponding edges, the connecting portions being rounding, the wide element overlapping an edge portion of the closure at one side ofk thegroove and thefnarrow element and rounded connecting portion being disposed within the said groove, and fastening means connecting the narrow` element with the bottom of the groove to admit of theweather strip having both a tilting movement and a movement edges to provide spaced lnarrow and wide elements and a connecting rounded portion and disposed `withfthe narrow 'element and rounded connecting portion within the said groove and the wide elementv overlapping ltheiedge of the closure at one side of the groove, headed fastenings Connecting the narrow element with vthe Vbottom of the groove yand having the heads spacedk from.

the bottom of the groove to ladmit of the strip rocking and moving bodily toward and from thev grooved edge of the Closure, and

siirings secured in thergroove and exertingV an outward pressure on the narrow element adjacent the rounded connecting portion.

In testimony whereof I affix my signaturel in presence of two witnesses.
